What properties do ceramics have? As we've already seen, the most important general property of ceramics is that they're refractory: they're rough-and-tumble materials that will put up with fair amounts of abuse in the most ordinary and extraordinary situations. Just consider, most of us tile our kitchens and bathrooms because ceramic tiles are hard, waterproof, largely resistant to scratches, and keep on looking good for year upon year; but engineers also put (very different!) ceramic tiles on space rockets to protect them against heat when they whiz back to Earth. If we're summarizing their properties, we can say that ceramics have: High melting points (so they're heat resistant). Great hardness and strength. Considerable durability (they're long-lasting and hard-wearing). Low electrical and thermal conductivity (they're good insulators).

Ceramic materials are special because of their properties. They typically possess high melting points, low electrical and thermal conductivity values, and high compressive strengths. Also they are generally hard and brittle with very good chemical and thermal stability. Ceramic materials can be categorized as traditional ceramics and advanced ceramics. Ceramic materials like clay are categorized as traditional ceramics and normally they are made of clay, silica, and feldspar. As its name suggests, traditional ceramics are not supposed to meet rigid specific properties after their production, so cheap technologies are utilized for most of the production processes.

A brief history of ceramics 23,000–25,000 BCE: Earliest use of human ceramics (for example, in figurines of humans and other animals made of pottery, discovered at Dolní Věstonice in the Czech Republic).     14,000BCE: Ceramic tiles are being made in India and Mesopotamia. 18,000–14,000 BCE: Earliest use of pottery vessels (for example, in Jiangxi, China ). 7500–6500BCE: First use of mud bricks. 6000 BCE: Earliest known kiln (Yarim Tepe site in modern Iraq) 5000–8000 BCE: First use of glazes. Nile Valley of Egypt. According to [https://books.google.co.uk/books?id=PAZR-A9Ra6EC] 3500–5000BCE: Earliest use of glass (according to Eric Le Bourhis in Glass: Mechanics and Technology ). 3500–2500BCE: Invention of the potter's wheel . Mid-late 1900s: Development of effective glass and ceramic insulators for telegraphs and electric power distribution. 1940s: Development of ferrite magnets for such things as loudspeakers and electric motors. 1986: High-temperature s...
